Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With readOnlyHint and openWorldHint already declared, the description adds valuable behavioral context: the data window is 'what SWOGE indexed on-chain' and it discloses a minimum threshold ('below 5 judged tokens it does not compare'). It does not mention authentication or rate limits, but the added provenance and comparison limitations are substantive.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is front-loaded with the usage condition and then details the return value. It is information-dense and every sentence contributes, though it is somewhat long and could be slightly more structured for scanning.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema, the description thoroughly explains what is returned (swaps in 1h/24h, price change, share traded with 95% interval) and caveats (data window, minimum sample). This is complete for an agent to correctly interpret the tool's output without additional output documentation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents both parameters (including the quote flag and address format). The description adds no parameter-specific meaning beyond what the schema provides, so the baseline of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: 'track record of an address that launches tokens on Base (Clanker v4 or Zora)'. It explicitly lists the returned data—launches, swaps, price changes, share traded—making it clearly distinct from sibling tools like base_launches or wallet_intel.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The opening 'Use this when you need the track record of an address that launches tokens on Base' gives clear usage context. However, it does not name alternatives or state when not to use it, so it falls short of the 5-level criterion for explicit alternatives.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
